Other Parts Discussed in Thread: AMC1311
We are looking to use ISO224, but we need to measure unipolar DC signals. The IC has bipolar input/output and then we use a bipolar ADC (Delfino device). We only have unipolar input signals so we lose ½ of the resolution. The solution would be to add a negative offset so we can measure 0 to 24V input signals (-12V to +12V after the offset). Do you have any suggestion to accomplish this so we don’t have to reinvent the wheel?
Some requirements below (this is why the ISO224 was selected).
-needs to be pin compatible part for ISO7721D (in the small package, with a higher isolation voltage)
-we need 1000V working voltage
